- The following are reasons why randomized control trials (RCTs) are not used to investigate all research questions, except: a. RCTs can be expensive, which can make it difficult if funding is limited b. RCTs can be time-consuming, and it may take months and sometimes years to obtain final results c. For certain research questions and/or certain types of exposure variables, it may not be ethical to conduct an RCT d. RCTs are less valid than observational analytical study designsarrow_forwardCan you please answer this question How is point of testing an advantage compare to laboratory testing?arrow_forwardWhich of the following best describes the control group for this experiment? a) mating between male flies raised on maltose medium and female flies on starch medium.b) mating between male and female flies raised on starch medium in different populations.c)mating between female flies raised on maltose medium and male flies raised on starch medium.arrow_forward
- A group of researchers is studying the effect of saltwater concentration on metabolism in guppies. They separate their guppies into 6 groups, each containing 3 guppies. All groups will undergo one control trial and one experimental trial. The researchers then analyzed the results. What type of t-test did they use and what is the n of this experiment?
